A while ago there was a rumor about Katharine McPhee being engaged because she got photographed wearing a ring on her left ring finger. Don’t know why, but no one really believed she was engaged, turns out we should’ve.

Her future hubby, Nick Cokas, is only 42, he an actor (I mean wanna be one) and if to believe Katharine’s friends, absolutely crazy for her “fame”, I mean Katharine. Did I mention she is only 23?

“Katharine is bubbling over with excitement for her upcoming wedding,” a source says. She is all smiles when she talks about the planning. It sounds like everything is going very smoothly.

The couple met in 2005 when they performed in a Los Angeles theater production of The Ghost and Mrs. Muir. ”He took me up to my San Francisco (Idol) audition,” McPhee said. That’s when their relationship blossomed. “We totally fell in love,” she said.

As for the 19-year age difference, McPhee says that “was never really a concern. The two connect because “he just makes things really fun” and “we love business. We love going to meetings together and create things together.”

How much would you give them, half year, the entire year or two?
